All studies are conducted in laboratory conditions and focus on flow depth and velocity measurements. Investigated flows cover a wide range of complexity, e.g. propagation of waves, dam-break flows, slightly and fully aerated spillway flows as well as highly turbulent hydraulic jumps. Newimagingmethods are compared to different types of sensorswhich are frequently employed in contemporary laboratory studies. This classical instrumentation as well as the general concept of hydraulic modeling is introduced to give an overview on experimental methods. Flow depths are commonly measured by means of ultrasonic sensors, also known as acoustic displacement sensors. These sensors may provide accurate data with high sample rates in case of simple flow conditions, e.g. low-turbulent clear water flows. However, with increasing turbulence, higher uncertainty must be considered. Moreover, ultrasonic sensors can provide point data only, while the relatively large acoustic beam footprint may lead to another source of uncertainty in case of relatively short, highly turbulent surface fluctuations (ripples) or free-surface air-water flows. Analysis of turbulent length and time scales of surface fluctuations from point measurements is also difficult. Imaging techniques with different dimensionality, however, may close this gap. It is shown in this thesis that edge detection methods (known from computer vision) may be used for two-dimensional free-surface extraction (i.e. from images taken through transparant sidewalls in laboratory flumes). Another opportunity in hydraulic laboratory studies comes with the application of stereo vision. Low-cost RGB-D sensors can be used to gather instantaneous, three-dimensional free-surface elevations, even in flows with very high complexity (e.g. aerated hydraulic jumps). It will be shown that the uncertainty of these methods is of similar order as for classical instruments. Particle Image Velocimetry (PIV) is a well-accepted and widespread imaging technique for velocity determination in laboratory conditions. In combination with high-speed cameras, PIV can give time-resolved velocity fields in 2D/3D or even as volumetric flow fields. PIV is based on a cross-correlation technique applied to small subimages of seeded flows. The minimum size of these subimages defines the maximum spatial resolution of resulting velocity fields. A derivative of PIV for aerated flows is also available, i.e. the so-called Bubble Image Velocimetry (BIV). This thesis emphasizes the capacities and limitations of both methods, using relatively simple setups with halogen and LED illuminations. It will be demonstrated that PIV/BIV images may also be processed by means of Optical Flow (OF) techniques. OF is another method originating from the computer vision discipline, based on the assumption of image brightness conservation within a sequence of images. The Horn-Schunck approach, which has been first employed to hydraulic engineering problems in the studies presented herein, yields dense velocity fields, i.e. pixelwise velocity data. As discussed hereinafter, the accuracy of OF competes well with PIV for clear-water flows and even improves results (compared to BIV) for aerated flow conditions. In order to independently benchmark the OF approach, synthetic images with defined turbulence intensitiy are used. Computer vision offers new opportunities that may help to improve the understanding of fluid mechanics and fluid-structure interactions in laboratory investigations. In prototype environments, it can be employed for obstacle detection (e.g. identification of potential fish migration corridors) and recognition (e.g. fish species for monitoring in a fishway) or surface reconstruction (e.g. inspection of hydraulic structures). It can thus be expected that applications to hydraulic engineering problems will develop rapidly in near future. Current methods have not been developed for fluids in motion. Systematic future developments are needed to improve the results in such difficult conditions.}, language = {en} } @article{BungCrookstonValero2020, author = {Bung, Daniel Bernhard and Crookston, Brian M. and Valero, Daniel}, title = {Turbulent free-surface monitoring with an RGB-D sensor: the hydraulic jump case}, series = {Journal of Hydraulic Research}, journal = {Journal of Hydraulic Research}, publisher = {Taylor \& Francis}, address = {London}, issn = {1814-2079}, doi = {10.1080/00221686.2020.1844810}, year = {2020}, language = {en} } @article{BungErpicumTullis2020, author = {Bung, Daniel Bernhard and Erpicum, S{\´e}bastien and Tullis, Blanke P.}, title = {Advances in hydraulic structures engineering}, series = {Journal of Hydraulic Engineering}, volume = {147}, journal = {Journal of Hydraulic Engineering}, number = {1}, publisher = {ASCE}, address = {Reston, Va.}, issn = {0733-9429 (Druckausgabe)}, doi = {10.1061/(ASCE)HY.1943-7900.0001851}, pages = {1 Seite}, year = {2020}, language = {en} } @inproceedings{BungHildebrandtOerteletal.2008, author = {Bung, Daniel Bernhard and Hildebrandt, Arndt and Oertel, Mario and Schlenkhoff, Andreas and Schlurmann, Torsten}, title = {Bore propagation over a submerged horizontal plate by physical and numerical simulation}, series = {Coastal engineering 2008 : proceedings of the 31st international conference; Hamburg, Germany, 31 August - 5 September 2008 ; Vol. 4}, booktitle = {Coastal engineering 2008 : proceedings of the 31st international conference; Hamburg, Germany, 31 August - 5 September 2008 ; Vol. 4}, editor = {McKee Smith, Jane}, isbn = {9814277401 ; 9789814277402}, pages = {3542 -- 3553}, year = {2008}, language = {en} } @inproceedings{BungOertelSchlenkhoffetal.2010, author = {Bung, Daniel Bernhard and Oertel, M. and Schlenkhoff, A. and Schlurmann, Torsten}, title = {Flash flood awareness and prevention in Germany}, series = {Early warning for flash floods : international workshop, Praha 2011 : workshop proceedings}, booktitle = {Early warning for flash floods : international workshop, Praha 2011 : workshop proceedings}, editor = {Obrusnik, Ivan}, organization = {Czech Hydrometeorological Institute}, isbn = {978-80-86690-91-9}, pages = {34 -- 40}, year = {2010}, language = {en} } @inproceedings{BungOertel2014, author = {Bung, Daniel Bernhard and Oertel, Mario}, title = {Manipulation of non-aerated cavity flow on a stepped spillway model}, series = {3rd European IAHR Congress : April 14 - 16, 2014, Porto}, booktitle = {3rd European IAHR Congress : April 14 - 16, 2014, Porto}, publisher = {Univ. of Porto}, address = {Porto}, organization = {International Association of Hydro-Environment Engineering and Research}, year = {2014}, language = {en} } @inproceedings{BungOertel2019, author = {Bung, Daniel Bernhard and Oertel, Mario}, title = {Wave breaking over a submerged horizontal plate: Optical Flow, LES and RANS}, series = {E-proceedings of the 38th IAHR World Congress September 1-6, 2019, Panama City, Panama}, booktitle = {E-proceedings of the 38th IAHR World Congress September 1-6, 2019, Panama City, Panama}, doi = {10.3850/38WC092019-0509}, pages = {3690 -- 3698}, year = {2019}, language = {en} } @inproceedings{BungPagliara2013, author = {Bung, Daniel Bernhard and Pagliara, S.}, title = {Proceedings of the International Workshop on Hydraulic Design of Low-Head Structures : Aachen, Germany, February, 20-22, 2013 / D.

The flow velocities, obtained using a basic Horn-Schunck method for estimation of the optical flow coupled with an image pyramid multi-resolution approach for image filtering, compare well with data from intrusive conductivity probe measurements. Application of the Horn-Schunck method yields densely populated flow field data sets with velocity information for every pixel.

Due to the step-induced macro-roughness, the flow field becomes more turbulent than on a similar smooth-invert chute. For this reason, cascades are oftentimes used as re-aeration structures in wastewater treatment. However, for stepped spillways as flood release structures downstream of deoxygenated reservoirs, gas transfer is also of crucial significance to meet ecological requirements. Prediction of mass transfer velocities becomes challenging, as the flow regime differs from typical previously studied flow conditions. In this paper, detailed air-water flow measurements are conducted on stepped spillway models with different geometry, with the aim to estimate the specific air-water interface. Re-aeration performances are determined by applying the absorption method. In contrast to earlier studies, the aerated water body is considered a continuous mixture up to a level where 75\% air concentration is reached. Above this level, a homogenous surface wave field is considered, which is found to significantly affect the total air-water interface available for mass transfer. Geometrical characteristics of these surface waves are obtained from high-speed camera investigations. The results show that both the mean air concentration and the mean flow velocity have influence on the mass transfer.

This study developed a conceptual model of a mainstream deammonification plant, designed for 30,000 P.E., considering possible solutions corresponding to the challenging mainstream conditions in Germany. In addition, the energy-saving potential, nitrogen elimination performance and construction-related costs of mainstream deammonification were compared to a conventional plant model, having a single-stage activated sludge process with upstream denitrification. The results revealed that an additional treatment step by combining chemical precipitation and ultra-fine screening is advantageous prior the mainstream deammonification. Hereby chemical oxygen demand (COD) can be reduced by 80\% so that the COD:N ratio can be reduced from 12 to 2.5. Laboratory experiments testing mainstream conditions of temperature (8-20°C), pH (6-9) and COD:N ratio (1-6) showed an achievable volumetric nitrogen removal rate (VNRR) of at least 50 gN/(m3∙d) for various deammonifying sludges from side stream deammonification systems in the state of North Rhine-Westphalia, Germany, where m3 denotes reactor volume. Assuming a retained Norganic content of 0.0035 kgNorg./(P.E.∙d) from the daily loads of N at carbon removal stage and a VNRR of 50 gN/(m3∙d) under mainstream conditions, a resident-specific reactor volume of 0.115 m3/(P.E.) is required for mainstream deammonification. This is in the same order of magnitude as the conventional activated sludge process, i.e., 0.173 m3/(P.E.) for an MWWTP of size class of 4. The conventional plant model yielded a total specific electricity demand of 35 kWh/(P.E.∙a) for the operation of the whole MWWTP and an energy recovery potential of 15.8 kWh/(P.E.∙a) through anaerobic digestion. In contrast, the developed mainstream deammonification model plant would require only a 21.5 kWh/(P.E.∙a) energy demand and result in 24 kWh/(P.E.∙a) energy recovery potential, enabling the mainstream deammonification model plant to be self-sufficient. The retrofitting costs for the implementation of mainstream deammonification in existing conventional MWWTPs are nearly negligible as the existing units like activated sludge reactors, aerators and monitoring technology are reusable. However, the mainstream deammonification must meet the performance requirement of VNRR of about 50 gN/(m3∙d) in this case.}, language = {en} } @techreport{ChristGrossRenz1998, author = {Christ, Ansgar and Groß, Rolf Fritz and Renz, Ulrich}, title = {Str{\"o}mungs-, Filterkuchen- und Abreinigungsmodelle f{\"u}r Heißgasfilter, Teilvorhaben "Numerische Simulation des Abreinigungsvorganges und der Rohgasstr{\"o}mung"}, doi = {10.2314/GBV:50431601X}, pages = {117 Seiten}, year = {1998}, language = {de} } @techreport{ChristGrossRenz1998, author = {Christ, Ansgar and Groß, Rolf Fritz and Renz, Ulrich}, title = {HGR: Untersuchung zur Minimierung von gasf{\"o}rmigen Schadstoffen aus Rauchgasen bei der Heißgasfiltration}, doi = {10.2314/GBV:504318411}, pages = {141 Seiten}, year = {1998}, abstract = {Gas- und Dampfturbinen-Kraftwerke mit Druckwirbelschicht- oder mit Druckvergasungsverfahren erm{\"o}glichen die Verstromung von Kohle mit hohem Wirkungsgrad und niedrigen Emissionen.

Complimenting acoustic techniques, significant progress has been made for the development of new optical methods. Computer vision techniques can help to extract new information, e. g. high-resolution velocity and depth data, from videos captured with relatively inexpensive, consumer-grade cameras. Depth cameras are sensors providing information on the distance between the camera and observed features. Currently, sensors with different working principles are available. Stereoscopic systems reference physical image features (passive system) from two perspectives; in order to enhance the number of features and improve the results, a sensor may also estimate the disparity from a detected light to its original projection (active stereo system). In the current study, the RGB-D camera Intel RealSense D435, working on such stereo vision principle, is used in different, typical hydraulic modeling applications. All tests have been conducted at the Utah Water Research Laboratory. This paper will demonstrate the performance and limitations of the RGB-D sensor, installed as a single camera and as camera arrays, applied to 1) detect the free surface for highly turbulent, aerated hydraulic jumps, for free-falling jets and for an energy dissipation basin downstream of a labyrinth weir and 2) to monitor local scours upstream and downstream of a Piano Key Weir. It is intended to share the authors' experiences with respect to camera settings, calibration, lightning conditions and other requirements in order to promote this useful, easily accessible device. Results will be compared to data from classical instrumentation and the literature. It will be shown that even in difficult application, e. g. the detection of a highly turbulent, fluctuating free-surface, the RGB-D sensor may yield similar accuracy as classical, intrusive probes.}, language = {en} } @incollection{DautzenbergGrossRenz1996, author = {Dautzenberg, H. and Groß, Rolf Fritz and Renz, Ulrich}, title = {Meßtechnik auf dem Pr{\"u}fstand: Forschung zur Heißgasfiltration}, series = {Virtuelle Instrumente in der Praxis.

It addresses basic building physics performance at a laboratory and full-scale level, and the preparation of design guidance for commercial, industrial and residential buildings. It includes the development of design tools to assist users in assessing whole-building performance, and calibrates these tools against whole-building measurements, which will be obtained from this research. Opportunities for renewable energy and other energy-saving features will be assessed. This project focuses on objectives that are of particular interest for the design of new steel constructions regarding energy efficiency. ETHICS investigates the as-built performance by on-site tests regarding air tightness and heat transfer properties of the building envelope and by monitoring the energy consumption and thermal comfort of selected up-to-date steel buildings. As energy efficiency is a key requirement for design and construction of buildings in the future, this project provides well-founded scientific data, which prove the high energy performance of current steel constructions and work out details for further improvements to maintain and extend the position of steel products in the construction sector.}, language = {en} } @article{FeldmannDoeringKuhnhenneetal.2008, author = {Feldmann, Markus and D{\"o}ring, Bernd and Kuhnhenne, Markus and Sedlacek, Gerhard}, title = {Zum Thema "Nachhaltigkeit" in der Stahlbauindustrie}, series = {Stahlbau}, volume = {Vol. 77}, journal = {Stahlbau}, number = {Iss. 10}, issn = {0038-9145}, pages = {713 -- 720}, year = {2008}, language = {de} } @inproceedings{FeldmannPyschnyDoeringetal.2012, author = {Feldmann, Markus and Pyschny, D. and D{\"o}ring, Bernd and Kuhnhenne, Markus}, title = {Life cycle assessment of steel constructions}, series = {Life-cycle and sustainability of civil infrastructure systems : proceedings of the Third International Symposium on Life-Cycle Civil Engineering (IALCCE'12) : Vienna, Austria, October 3-6, 2012}, booktitle = {Life-cycle and sustainability of civil infrastructure systems : proceedings of the Third International Symposium on Life-Cycle Civil Engineering (IALCCE'12) : Vienna, Austria, October 3-6, 2012}, publisher = {Taylor and Francis}, address = {Hoboken}, organization = {International Symposium on Life-Cycle Civil Engineering <3, 2012, Wien>}, isbn = {978-0-203-10336-4}, pages = {321}, year = {2012}, language = {en} } @inproceedings{FellinKingKirschetal.2009, author = {Fellin, Wolfgang and King, Julian and Kirsch, Ansgar and Oberguggenberger, Michael}, title = {Uncertainty modelling and sensitivity analysis of tunnel face stability}, series = {Safety, reliability and risk of structures, infrastructures and engineering systems : proceedings of the tenth International Conference on Structural Safety and Reliability (ICOSSAR 2009), Osaka, Japan, 13-17 September 2009 / ed.: Hitoshi Furuta ...}, booktitle = {Safety, reliability and risk of structures, infrastructures and engineering systems : proceedings of the tenth International Conference on Structural Safety and Reliability (ICOSSAR 2009), Osaka, Japan, 13-17 September 2009 / ed.: Hitoshi Furuta ...}, publisher = {CRC Pr.}, address = {Boca Raton, Fla.

In this paper, we combine laboratory experiments performed at the University of Innsbruck with current methods of uncertainty and sensitivity analysis for assessing adequacy, predictive power and robustness of the models.
